The railroad swing truss bridge at Cotter was designed to swing open so that steamboats (with tall smoke stacks) could pass through when going up or down stream.
It is common that many call this type through bridge as a "Pratt" Truss. But it is not. It is a "Howe" Truss.
This through truss bridge at Cotter is really a "Howe" truss design. A Howe Truss is an upside-down Pratt.
For a "Pratt" type, when supported by piers on each end, the diagonal structural members (within the truss) slope downward in the direction to the center of the span.
For a "Howe" type, when supported on each ends by piers,
structural diagonal members within the truss slope downward in the direction of the ends of the span.
In the "Howe" design, (all but one) vertical structural members are in tension, directly holding up the bridge's deck below.
For the "Pratt" type, when supported on each end by piers, within the truss it has sloped diagonal downward members that point towards the center of the truss; and those "diagonal" members are in tension holding up the bridge's deck below. Just the opposite as in the Howe design where it pulls up "vertically".
If the Cotter "Howe" bridge was swung open, then the center bridge pier holds up the entire through truss bridge. The end piers no longer hold the truss bridge up. During the open period all the prior tension structural members become in compression. During the open period all the prior compression structural members become in tension. In the open position the bridge become a double cantilever structure. Since the Howe truss design has structural diagonal members sloping downward towards the bridge's ends, when swung open, those sloped members are pulling on the bottom of the truss, to effectively hold up the ends from straining downward.
The Howe and Warren truss designs are desired for swing bridges with only a center pior (when opened). For truss bridges that are not to be swung open, the truss can be either a Pratt, a Howe or the Warren design.
Take a look at;
no trusses are standing, the other bridge is not far from collapsing in places
I think it would be prudent not to say that the bridge
swung open only once! That should be deleted. It is not needed in the description.
There are some people in Mountain Home, AR
that think that is not the case.
A few steamboat records imply they went
north from Buffalo City.
Just a few times, but can not be proven since
the St. Louis Iron Mountain and Southern Railroad
did not have any records. Many steamboats even operated at night.
Yeah, this isn't railroad.
Random internet guy here--- I think the Barkshed bridge is WPA/CCC road bridge circa late 1930s, not MN&A. The MN&A in Stone County was to the Southwest and there was a stop at Arlburg. This is fresh to me because parts of the Ozark HIghlands Trail and the Buffalo River Trail are on old road beds, and we've hiked both sections recently. Really nice trails, and the Buffalo River Trail downstream from Gilbert leads to the piers of the MN&A bridge over the Buffalo.
What a jewel. Taken November 2018
To get to the other side.
Why did you add imagery of the bridge in Texas at the original location?
My parents were both born and raised in Cleburne County and my Grandma lived in Heber Springs on Hwy 110. From 1965 to 1972 we made several trips from Fresno California in our 1965 Chevy Impala.I remember several times Daddy would drive across that one lane bridge really fast, and as soon as we got to the other side he'd flip a U-turn and we would watch that thing swing back and forth! It was so exciting! Of coarse my mom made Daddy pull the car over so she could get out. But my sister and I would scream and giggle the whole time! I really miss Daddy...great memories.
Just saw the video showing the bus crossing the bridge.Can't believe how the bridge didn't collapse from the weight.The video shows everything.You can see the bridge deck moving under the bus.
Touring coach GVWR 53,000 lb or roughly 25 tons. Find and fine the bozo and his company.
Are you sure that the weight of the bus was "at least three times" the 10 ton rating? A quick google has much lower values than that.
that states a typical (transit, can't find tour bus info) bus is curb weight of 20-33,000lb (10-16.5 tons), and GVWR 30-44,000lb (15-22 tons). Still way heavier than should be on the bridge, but 60,000lb/30 tons is far higher than I'd expect given that the maximum allowed weight for a semi (with far more axles) is generally 72,000lb/36 tons.
Fortunately, the bridge appears to have suffered no damage according to ARDOT, but the bus driver needs to fined at the very least
Let's catch the stupid bus driver for crossing this fragile bridge with an overloaded tour bus, shall we? This is SO not cool! https://bridgehunterschronicles.wordpress.com/2018/10/16/ove...
I did a quick field visit to this bridge today. It is still open to traffic. The new bridge is still a long ways from being completed so you probably have at least a few more months to see this bridge. The Center span of the new bridge still has no I beams in place. I was surprised as I figured that it would be much farther along by this time.
That being said, you will want to get here as quick as you can. This bridge will not be around forever and it is very much worth seeing.
I drove across this bridge today. All I can say is, wow!
I did not have time to take photos and document the bridge because I was trying to get to Paducah, Kentucky. The bridge is open to traffic and the road is paved at both ends. This bridge is easy to visit if you are driving past on Highway 67.
I'm pretty sure this bridge has been replaced.
I recently purchased an old photo album of postcard size photos of construction of the mulberry river bridge Franklin co.Arkansas. They have white lettering on front with info like a rppc just no postage or ink on reverse. If anyone is interested in purchasing email me. They have interesting equipment and crews at work. Some pages are written with markings for example " M-3 B-15" thanks.
Thanks for sharing Tony!

I fish this area a lot and live only mins away. This bridge is referred to locally as "Old Town Bridge". Pretty neat site y'all have here. I just stumbled upon it looking online for bridges to fish. Lol Next time I'm fishing in the area I'll snap y'all a pic.
When I was going to college at ASU in Jonesboro, and going home to Searcy, ever so often I'd take US 64. More than once, I got stuck on this bridge with farm equipment coming towards me. Driving in reverse off this bridge wasn't a lot of fun.
Creation of the Gardens began in 1956.
This was not a Mo Pac bridge. It was part of the Missouri North Arkansas or Missouri and Arkansas line. It was removed not long after the line from Harrison to Cotton Plant was removed circa 1947-48.
Actually these first nine images are of the old 70 bridge and not the 7 bridge. As I mentioned in a previous comment, I have crossed this bridge countless times since 1975. I can find old photos and more current ones to prove that these first nine photos are NOT the 7 bridge.
That first picture is the 70 bridge not the 7 bridge. I can go back and tell you which numbers are the 70 bridge versus the 7 bridge. I have crossed these bridges countless times since 1975.
Work has started in the restoration of this bridge, which is estimated to cost $2.8 million.
You can also see pictures and more information about the organization which was founded to preserve the bridge, etc at: https://www.salinecrossing.com/ (Photos from May 2018: https://www.salinecrossing.com/photos)
Hi, would love for Mr.Houp to get in touch with me. I read his book on the Plumlee family when I was 12 years old. I'm 45 now and I have been researching on the family for over 33 years now. Thank you Mr. Houp. I just missed you about 3 or 4 years ago I was in Berryville Arkansas at the court house researching. The kind ladies told me I just missed you by about 10 minutes and that you were there researching Bridges
7-7-18 Is the bridge intact now ? Is it near County Road 36 ?
We don't know, we're not a governmental agency.
Why it’s been closed for months ???
How much longer ???

There is now a Facebook page dedicated to saving this bridge: https://www.facebook.com/Bigwhiteriverbridge/
According to the latest update, the group was given an additional 45 days on May 24th to save the bridge.
NBI suggests this was likely abandoned circa 1962.
I visited this bridge on 5-13-2018. It is totally within the bounds of Craighead County by approximately 1/2 mile.
A few pictures taken 4-18-2018.
It's hard for me to believe that the White river was a navigable steam to begin with. That being said,I think the placement of the the swing pier could interrupt the natural flow of the river and cause it to change course. I've been to Cotter and the river there looks more like a float trip stream. Can't imagine any steam boats going by here.
Please stay out of the tunnel for your safety. My aunt said be very careful where you go some of the neighbors are not so friendly.
Yes, there was a bridge before this bridge per HAER documentation, but I am not sure what type it was. It was noted that the previous bridge was in good condition, the main reason it was replaced was its design load capacity was not high enough. So it is quite possible you found remnants of the previous bridge.
I am sad to report that this bridge has been demolished. According to the AR Dept. of Transportation, the date plaque from the bridge has been donated to the Natural Dam Community Center to be displayed there. The photo below was taken a few days before the bridge was taken down.
When was this railroad bridge built?
downstream of the current bridge, back in the woods on the opposite side of the river, there appears to be another base for a previous bridge...I know this one was built in 1931, but was there one before this? Pic attached.
Judge gives 90 days to save Clarendon Bridge
The destroyed bridge was a truss, but its replacement isn't, so this should be 2 separate entries. One for the bridge that was destroyed by a tornado, another entry for the replacement, plus a third entry for the ferry AHTD ran while the new bridge was being built.
This bridge is more commonly known as the Edgemont Bridge, connecting Greers Ferry to Edgemont across Greers Ferry Lake.
The current bridge is also the second bridge at the site. "Rehabilitated" is a gentle word for "replacing entire span after original bridge was destroyed by a tornado."
For more information, including updates on who built the new bridge, see Page 13 of this Summer 1985 issue of Arkansas Highways, published by the state's transportation department: https://tinyurl.com/y825mol5
You'll have to ask HAER about the milkman. It's their photo.
Drove over this one last year. An African American family was walking down the side of the road. I briefly crossed the centerline to give them room.
As I progressed farther down the road, another driver got very irate with me for giving them room. Crazy! I hope it was not racist.
Can somebody please dumb this down to a Kardashian level for me? I am not quite getting the connection between this bridge and the milkman...
I visited this bridge on 2-27-18. Based on the level of completion on the new bridge, I'm guessing this one will survive one more Summer
This bridge is just north of several bridge replacements along US 63. It does not appear to be endangered at this time.
Bridge has been closed due to flood damage to one of the timber columns
Bridge is open with 3 Ton Weight Limit and 8 foot vertical clearance.
Bridge is closed to the public behind a locked gate. Possibly a privately-owned hunting area?
I visited this on 27 January and work has yet to begin on its replacement. Only thing I saw were some survey markers.
I visited this bridge on 27 January. Work has just barely begun (mostly clearing vegetation) so there is still time to visit before it goes away.
This photo is leaving Shaw Bridge, on Grand headed into Haskell, Arkansas. This photo is to show the road you must travel to get there. Dirt/grated gravel.
Shaw Bridge 2017
This photo is from 2017. Shaw Bridge has quite a bit of character. The bride is a one lane Pony Truss. The bridge has been graffiti pained over the years, but looking over the side of the bridge offers a calendar picture view. The road to get there is grated dirt/gravel, but a trip worth going to.
The Fort Chaffee Redevelopment Authority was originally going to reuse this bridge, but has changed their mind. It is now scheduled to be demolished by the end of January 2018.
Bridge is gone
Here are construction plans for the suspension bridge.
However, I believe that the suspension bridge crossed Kings River a little further north as shown here:
New bridge is complete and open to traffic. The sharp bend in the road at US 71 has been removed.
I have looked for pictures of this bridge for years. I remember being a three-year-old riding with my mom to Little Rock from Dardanelle. Crossing this bridge brought fear to me because the bridge was so narrow. I was terrified of it. Now I can see the beauty in it. Thank you for posting this picture.
They are in the final stages of completion of a new bridge being built on the south side of the existing bridge. It has been elevated and a new road is built to it, eliminating the hill downward to it. It looks safer - due to numerous wrecks that have occurred there in the past several years with gas industry trucks.
I don't know what they are planning with the old bridge.
Enjoyed this gem today! What an awesome old bridge
Is there still river traffic through bridge; I have 50' boat, wish to navigate black river to black rock????
Excellent news article about an award for this project. http://thecabin.net/local/news/2017-11-05/bridge-project-rec...
Took a walk out there this afternoon. My (amateur) opinion is that this bridge was built for this site, but was raised about two feet in 1928. The cut stone footing at the south end has a poured concrete filler on top of it, supporting the through girder span. Fresh heavy limestone riprap is evidence of a long-fought battle with flood waters at this site. In the surrounding woods there are piles of flood debris all the way to track level. Thanks to Gene and all the others here. I've ridden through this bridge several times, but never noticed what an interesting site it is.
They dedicated this bridge today. Words can not express .... always grateful to Bach gang and our clients were outstanding. Made a lot of friends. Congratulations to All of them. Hayden took this photo.
This bridge is still drivable, but the road is in rough shape.
Me, mom and family were some of the first to walk across the Helena bridge on opening day in July 1961. I was 12 years old, great memories! Couldn't believe we didn't have to take the ferry boat anymore to visit relatives in Mississippi.
Loosely translated to WOW Just wow!

FOR IMMEDIATE RELEASE Conway, Arkansas - Holt, Michigan
Springfield Bridge, a rare King Iron Bridge Co, bowstring through truss was restored for pedestrian use at Lake Beaverfork in Conway, Arkansas by Workin' Bridges, a non profit dedicated to historic bridge preservation and Bach Structural and Oranmental Steel (BACH Steel) of Holt, Michigan. Six years after the completion of a study by Nels Raynor of BACH Steel and Julie Bowers for Workin' Bridges, the historic bridge restoration project was successfully completed. The success was due to a rare collaboration between the City of Conway, Faulkner County, and Dr. Ken Barnes of the Faulkner County Historical Society who was essential in the writing and successful grant application and petitioning the City of Conway to find a place to move the bridge. Permission to move was granted by the National Park Service for this structure that is listed on the National Register of Historic Places. A dedication to the restoration and future of this iron bowstring will be held Saturday, September 23rd at 10:00 am at Beaverfork Lake Park in Conway, Arkansas.
The iron truss was fabricated in 1871 and erected in 1874 over E Cadron Creek between Faulkner and Conway Counties as the first and oldest highway bridge built for farm to market requirements by the Arkansas Department of Transportation. The bridge restoration was funded by City of Conway tourism dollars used for parks, Faulkner County equipment, expertise and funds for the extra crane, with the help of Metroplan which allowed the restructuring of grant funding to allow preservation to move forward.
The bridge was removed from the Cadron in November of 2016. The BACH Steel Rivet Gang went to work with the disassembly and marking the members for transportation to a paint removal company in Little Rock, managed by Snyder Environmental. Workin' Bridges was then given the job of designing the new substructure at Lake Beaverfork, engineered by James Schiffer of Schiffer Engineering Group of Traverse City, Michigan.
Once the caissons were designed, drilled, formed and poured, and covered with riveted columns repairs to the bridge trusses began. Nels Raynor of BACH Steel is the premier bridge restoration craftsman throughout the United States that specializes in restoring bridges the old fashioned way. "In Kind" restoration means that parts are replaced with similar parts, rivets replaced with rivets and if new parts are required they are fashioned with care. When asked Raynor stated: "This one stands out as one of the most beautiful. I wish there were more people like those of Conway and Faulkner County. Those who wish to protect and save their hesitate. It's part of my life's work to preserve those structures. My company has been bless with finding those with the same passion inmy partners Derek and Lee Pung, Andy Hufnagel and Brock. Behind the scenes we have my daughter Heather Raynor, Nathan Holth and Jim Schiffer. We want to thank everyone for giving us the creative freedom to make this one of the most memorable and beautiful bridges we have ever been involved with."
Jack Bell, Chief of Staff for the City of Conway, Mark Ledbetter, Director of Roads for Faulkner County, Steve Ibbotson, Director of Parks for the City of Conway and Judge Baker were the team that provided the collaborative efforts to make this a successful project. They teamed up for all of the site requirements, from building a road and crane pad to the old location on Cadron Creek, to building the roads and crane pad for the reset at Lake Beaverfork. They utilized reclaimed stone from the original abutments to sculpt the new location with retaining walls and provide a bench for viewing. Bell said, “The partnership between Workin’ Bridges, BACH Steel, Faulkner and the City of Conway was essential to bring this project to fruition. A significant piece of Faulkner County history has been saved and an iconic amenity has been added to our Parks system."
New railing required by law was designed by Raynor and Gang who were able to provide historically accurate laced and riveted railing, using requirements for today's pedestrians. The rail was then sent to Conway, where the local historical society teamed up with Workin' Bridges to promote the "Paint the Rail" campaign. The campaign successfully contributed the funds needed to coat the rail, using a PPG product delivered by Furgerson Brothers Painting.
The restoration will be featured in a documentary filmed by Terry Struass of Ultimate Restorations and should be available for viewing on PBS and through Amazon Prime in the fall of 2017. The project was also documented by Workin' Bridges with the aid of Nathan Holth of HistoricBridges.org. The bridge was built by craftsmen and the record of their work, the "craftsman's record" was evident in each cast and riveted piece in the bridge said Raynor. "To think that this all started six years ago with a site visit to Arkansas with my son Brock and Bowers with Workin' Bridges. What this bridge has become today is just amazing to me and I have been involved with many bridge projects".
It is a testament to the fact that we work better together, always have. The collaboration made a very big bridge project manageable, and used resources in a way that reduced time and material cost", stated Bowers from her office in Holt, Michigan. "One never knows if a site visit that renders real numbers for project evaluation will become a job. These bridges take a lot of time, craftsmanship and money, but in the end it is all about making memories. The collaboration worked well and rendered a project that could have cost far more into an affordable package for the parks system."
More information about the bridge, pictures from the process can be found at Springfield Bridge on Facebook. Questions may be directed to Julie Bowers at email@example.com.
The bridge was completed in the summer of 1929 to make a passage way between the town of Garfield and Eureka Springs. The "Great Depression" came that winter, and there was no money to complete the connecting road to the new bridge. For five years a fine concrete bridge spanned the river, but there were no approaches to it, and there was no road to get to it. Consequently, it became known as the "Lost Bridge." The bridge stood isolated until 1934, when the approaches were built and the road was completed. On 7 May, 1943 a flood destroyed the bridge and later a concrete low-water crossing was built near the wrecked bridge. In March 1964, as Beaver Dam was completed and the lake filled, the low-water crossing and the remains of the Lost Bridge were flooded, never again to be used. Today they are under approximately 190 feet of water.
This bridge was just reopened http://www.nwahomepage.com/news/washco-bridge-reopened-after...
Nicely done. Congratulations to involved!
Othmar H. Ommann winner for SURE!
Looking great! When your bridge is on the verge of collapse, just call Julie, Nels, Rivet and the Gang!
It's been finished. Awesome work by Bach....
Finished it up . It looks lovely.
This bridge is being replaced but is still open to traffic. Sorry but I don't have a photo.
Nearing completion....weather delays.
Here is my thinking....Picture 3 is dated 7/6/19 Roughly when the Index (Highway) bridge opened. It is looking from south to north. Index Bridge is on the right and the 1900 Railroad bridge is on the left.
The railroad bridge is lower. The bridge on the left (and lower) is a Parker Through Truss (Rounded top...Camelback).
This bridge had a flat top (Pratt.)
Right crossing wrong place on the timeline?
The number COULD be a photo#, but from looking at the lay of the land today, low bank on the south and the high bank on the north, this almost has to be the south bank.
This bridge was obviously once located on a public road and relocated here at some point. The question is what road and what stream did it cross? We will probably never know.
Yeah whatever, save it til December!
..............Othmar H Ammann awards photograph of the year..............Just Saying
First dawn over the inlet at Beaverfork Lake.
It would get my vote. Julie, Nels, and the gang have done a smashing job with this beauty.
I was happy to see a certain Whipple from my old stomping grounds win last year, but even back then I figured that this Bowstring would be in the running. This year, it is #1 in my book so far.
Seems like this may qualify for Bridge of the year Othmar Awards. What are views of the titans?
This is the old bridge on Blacksferry Road, I grew up right down the road from it where the road splits into Water Valley & Blacksferry Roads. There is a bridge in Dalton, where I now live 5 miles from and a bridge on highway 90, as well as a bridge on hwy 62, which all cross the Eleven Point River. Kilo Vista is actually a member camp site where you can see where the old bridge once was. You can also see where the old bridge was at Dalton. The old bridge on Blacksferry Road had a date stamp, I guess you could call it, on the top part of the bridge overhead. It had the date, with names of the people who built or probably funded the bridge, with Canton, Ohio on the bottom of the license plate like trademark.
Bridgehunter went through some growing pains several years ago. Hopefully those days are behind us and we can all let bygones be bygones. This site has been much more peaceful lately.
Randall Houp & anyone who reads this page i owe you all an apology. I am sincerely sorry for being so argumentative with Randall Houp and anyone else on this site and i am embarrassed i said these things here for all to see. For what its worth i am on a medicine now :) which makes for a kinder-gentler Charlie but am not very active in bridge stuff anymore. Best Wishes to all and happy bridge hunting.
My family camped there Memorial Day weekend and the bridge is fully functional. We had some flood waters that left the creek high enough for daring folks to jump off the bridge into the creek! In 2016 I actually pulled my fifth wheel across it in the middle of the night, unaware of the highway entrance to the Anglers Resort, which rents cabins and numerous camp sites. Needless to say I was reluctant to pull the rig over the bridge but backing up my rig in the wee hours of the morning seemed worse. If your a bridge enthusiast, this is worth seeing.
This photo by Jerry Boyer. I didn't get to be there for the lateral connecting. Bummer for me.
Documentary continued with restoration of 2nd truss.
This is clearly not a Bailey truss. It looks like it is the same as the others is Logan county.
I'm pretty sure these are treadway M2 bridges. When the US Army would deploy them (WW II era) the space between the treads would be decked with 4 inches of plywood. The heavy traffic would stay on the treads. The lighter traffic that didn't have a wide enough track would put one wheel on the tread an another on the center decking.
Notice that in the deck photo there is open steel grate where the treadways are - and maybe concrete for the center deck?
These are a simple stringer design. So I'm changing the design details of the Logan county bridges.
Posted a photo i happened upon that shows a small bit of the rehabilitation construction on this bridge in '68-'70.
